Rebbecchi has been treating the 2-year-old pitbull mix since he was discovered after being left for dead in a pile of trash outside the Cobbs Creek Recreation Center on Tuesday.

It was a horrifying discovery prompted a community to band together to support Charlie, who was apparently used as a bait dog by those training dogs to fight.

The Pennsylvania Society for Prevention of Cruelty to Animals is still investigating the case. Gillian Kocher, an SPCA spokeswoman, said Saturday afternoon that there’s “nothing new to report (but) stay tuned.”

Rebbecchi told PhillyVoice that Charlie has improved from those perilous early hours.

“He’s comfortable and eating. He’s in reasonably critical condition,” said the veterinarian who is treating the dog for free. “He still needs a series of surgeries once he’s stable enough. But, he’s resting comfortably now.”

Of primary concern for Rebbecchi is a bacterial infection getting into the bloodstream and leading to sepsis.

The infection was prompted by maggots getting into open cuts and lesions as he sat in the trash near a Dumpster outside the South 63rd Street facility for an unknown period of time. Tissue is so deteriorated that there are fears that the dog could ultimately lose part of his face.

Bandages cover the side of Charlie's face that suffered the most damage.

“Right now, things look good,” he said, noting that the injuries may have proven fatal “if he wasn’t a pitbull.”

Nikki Rubino rescued Charlie from that trash heap along with her roommate Rob Rossi. She’s been to visit him several times now and said she’s seen some promising signs.

“I saw him (Friday) and he was awake and eating small, soft treats,” she said. “He still needs more surgeries and as a lot of healing to do.

“He’s sweet! He even gave some small kisses. He relaxed enough for belly rubs and fell asleep (after getting some).”

Charlie’s story prompted an outpouring from West Philadelphia and beyond to the point where Rebbecchi said people are calling with offers of donations, which he is not accepting.
